Here's a repair I am happy with.
The top of the companionway hatch (whatever it is called) was cracked which I did not think was an original design detail.
Examined the area with my usual great gusto for destroying the things I am trying to fix. Angle grinder and chisel revealed the cracks went all the way through to the space between the cabin roof and the liner. Ohh, not good.
Even the other side was coming apart.
Now I was really worried as the more I looked the more it seemed my boat was falling apart. Epoxy to the rescue!
After preparing the cracks for being epoxied, I squeezed it in, clamped it, put on fairing and more fairing [Not all at the same time]. I was happy that the epoxy I squeezed in would have made those bits of wood glue together tighter than they had been for years.
Finally I finished fairing and painted it. You can still see it is not perfectly flat, but it is way better than it was. Also you can see the side wash-board holders have been epoxied then painted with Botecote clear paint for a hard UV protective finish.
